Feedback for Install and Set Up SQL

- Following best practices, we should suggest using integrated security, if SQL Server is installed on the web server. This will not expose a password in web.config and is easy to configure.
- you do not need going to db users after creating a server account. Just click "user mapping" in the "Login New" window, select your database, enter "dbo" schema and grant owner role.
